The example references a 10uF capacitor used for CFF. If a much smaller capacitor, 10nF is used, is a protection diode necessary? Below is a screenshot in order to understand better the situation. Why it does that? I noticed previous posts about the bq34z bq34zg1 which are over 2 years old. This is a very low power application I’m a student at a university studying Computer Engineering and I’m currently working on a project with a small team to create a digital mixing console.
We have decided to use the 66AK2E02 processor.
The development board is nearly 1, dollars and that takes up a lot of our budget, I was told that I can request a keystone simulator for dztasheet 6 of Code Composer studio. I’ve tried using ccs v5. What we really want is is to use the simulator until we are sure its the processor we want.
Then we will either buy the processor itself and create our own datasneet or purchase the evaluation board if we can get our budget increased. I very new with CCS V6.
Memory usage decreases after some time. An earlier CCS V5. I’m currently testing and evaluting the Z-Stack with the Zlight2 development and I tried to operate the device with my philips hue hub.
Maybe this is the difference? So, my question is: Please give me a help. Start Code Composer Studio. The datasehet of the setup are quite similar to the TIDA reference design.
The copper tapes are 15mm wide, 0,mm thick.

The shields are mm, the references 20mm and the level 70mm long. The measuring gap is 4mm wide. As the insulator between the copper I used Tesa tape. The connections to the FDC are unfortunately unshielded 0,2mm copper wires. The whole setup does work quite reasonable. The submersed liquid reference is stable around 10pF, the environment reference about 7pF and both are suprisingly robust to external disturbances hand in the vicinity or touch.
The only problem is the level on CIN1, because it reaches saturation at 15pF already at a liquid level just about 10mm above the upper end of the liquid reference. When the system is switched on, the two references directly give a stable value whilst the level measurement slowly about 2 seconds goes up to saturation. The level measurement is not totally out of range, because I can get the value down to about 13pF when tilting the bottle and by this lowering the liquid level to the lower end of the copper strips.
As the OoP technology depends on symmetry of the setup, I guess that the accuracy of the test setup is not good enough. I further guess, that I do need to achieve a capacity-wise symmetry, not only a mechanical one. Even when I increase the manufacturing precision there still will be the unsymmetry of the wiring. I am building an inverter to produce a sine wave of KHz. So microphone will generate output voltages in the range of around 5.
But in the PCM chip, it is specified that 2. Why it is not working confidently in every read and write operation it gets hang I. I was looking at using a pair of 74act74 devices to divide my 60mhz trigger and provide my duty cycle adjustments. I am currently using LtSpice which is all I have. The devices from LT have got me to the 60mhz clock output and now my question is what device from TI, D flip flop or otherwise would be a good choice from here.
Any Help is appreciated. The task in my lab said to build a 2-bit binary up-counter and provided the following schematic:. So I built that circuit on a breadboard and wired Pin 1 and 13 together in parallel. The circuit would only increment the output from Pin 5 Q0. After some time of building, rebuilding, checking voltages, etc. Both FFs worked as expected. Then I wired the above circuit bit by bit to see when something went wrong.
I accidentally forgot to connect Pin 13 to the CLK input and suddenly the circuit worked. I checked all 5 chips I have and 2 locations on the breadboard.

None of my chips function in the circuit if both Pin 13 and Pin 1 receive the same signal. Which doesn’t sound right at all. I modeled the above diagram in a simulation program and it works fine and the datasheet says those pins are independent.
There is one other student who had the exact same issues I did. Everyone else got theirs to work. So did we get a bad lot, or is there something I’m not doing correctly? I’ve already turned the lab in, so I’m not looking for any answers to that end. I’m just generally curious as to why the first diagram doesn’t work. I appreciate any insight you guys can give!
Circuit as interpreted from the given diagram. The black spot is just a marking and the leftmost blue bus bar was used to send the Count signal to the lower 74LS08 chip and the 74LSAN chip.

And here is the one that works. The pictured loose jumper wire is the only one that I could use to connect header pin 2 to row No other jumper would work whatsoever, so I moved the input wire down instead.
Pin 13 is 74ls112na longer receiving a clock signal. Forums – Recent Threads http: Are you the publisher? Claim or contact us about this channel. Embed this content in your HTML.

Without Offset i only get the upper half wave. What to do to avoid this? Keystone Device Functional Simulator. Hello, I’m a student at a university studying Computer Engineering and I’m currently working on a project with a small team to create a digital mixing console.
When i debug, have the follow error: Zlight2 is not detected by Philips Hue Hub. Hi all, I’m currently testing and evaluting the Z-Stack with the Zlight2 development and I tried to operate the device with my philips hue hub. Installing Code Composer Studio v. Start Code Composer Studio Is there a way to adjust the capacity-wise symmetry of the whole setup? Thanks for any suggestions! PWM generation for modulatinf 7MHz carrier. Please share your comments to proceed further with this chip selection.
Dear I am unable to find why my writing a program to EEPROM works in few case and why not in other Why it is not working confidently in every read and write operation it gets hang I. In the enclosed file program works sucessfully. However if I add any othere read or write data to eeprom other than above code it dosent work for example, if this code if I insert in above code it wont work. The task in my lab said to build a 2-bit binary up-counter and provided the following schematic: Here are the circuits I built in case it helps.
Here are the wire designations: Q1 output And here is the one that works. Browse the Latest Snapshot. Browsing All Articles Articles.
