hello guys

i just want to generate a cosine waveform use DAC module
but i found that is can just generate freqency about 15hz and above,
and in my project i want to generate 1Hz cosine waveform,
so, it can be realized? how to configure? thanks

CAN 2.0 module , more UART module, maybe some functional safety module and software, compliance with IEC61508\IEC60730 standard,,etc

maybe can use nvs to storage the upgrade flag, software detect the flag and parameters in nvs when powerup, if detect need upgrade firmware then excute ota program, otherwise, start nomal sequence.
