AGM1264 GLCD problem
Thanks for the info, Bill. I will give this a try and see if I can get a heartbeat from the GLCD.

AGM1264 GLCD problem
So with the above setup, should I be seeing dots on the GLCD? The GLCD looks completely dead.

Question on TVS diode
Thanks,Jim. So with that logic, assuming approximately linear relationship, for a 14V board rating, I will have to use a 7V TVS?

Question on TVS diode
Thanks for the feedback,Kartman. Using the -A makes sense. The only reason I chose 24V is because the ambient temp. of my board is going to be 125C and I was thinking about...

Master in receive mode in SPI
Quote: What's the use of that delay? The delay is needed by the device. I will try your suggestion, David. Thanks.

Master in receive mode in SPI
Ok thanks. I have another question: With the same code as above, I get the clock generated and the zero transmitted every 50 us. How can I wait for 50 us only once and then start...

Master in receive mode in SPI
Thanks for the link and the info. Ok so now I am transmitting some dummy bytes after my data transfer is complete. Attached are the waveforms I got on the scope. Green is data...

Master in receive mode in SPI
I understand. Do I have to assert the SS pin low for the slave to respond? Or should I just send some dummy data from the master to keep the clock running and get data back from...

Master in receive mode in SPI
Thanks for the feedback. Before I change my functions, I am trying a basic test to check and see if the device responds. I am trying to take the SS pin low on the master side so...

Send a number of characters to SPI and stop
Ok I confirmed the output and both of them worked. Must have not flashed the chip right the first time.

Send a number of characters to SPI and stop
Ok I tried Chuck's idea and I am getting a continuous running display on the scope of 8 clock cycles with 0x01 and this pattern repeats (with the reset gap between the consecutive...
