Resolved! The signal Produced by DAC has errors
Hello,I am building and electric field sensor. The driver signal for it is produced via DAC of the STM32F767zi microcontroller. The signal is 4 kHz and is generated at a sampling speed of 80 kHz via DMA and TIM6. As you can see from the picture the s...
