Part Number: TSW1405EVM
Other Parts Discussed in Thread: AFE5809EVM

Hello,

when I evaluated afe5809evm using tsw1405evm, I found that only ‘1W_SERIAL.SVF’ is available in the firmware. Now I want to develop a new firmware for myself to use. Who can provide relevant source code? Thank you!

Hi，

thank you for your reply. I tried it with this firmware and couldn't use it. It should correspond to the first firmware in the picture in my last reply.

Hi,This one still has some problems.When I give a 1MHZ sine wave signal, I see 500KHZ when I receive the frequency in the FFT interface. When I test the sawtooth wave, the graph looks like this.

for 12x mode, you can use the ADS528x firmeware in the TSW1405. it should work as long as you play with LSB first, or MSB first. 2's comp and DC offset.

Thanks!
