Question about using DCMI in extra ADC(AD7768)
我尝试使用 STM32L4R9 与 AD7768 通信，使用 8 个通道。我想知道的是：是否可以使用 DCMI 建立 AD7768 与微控制器之间的通信（微控制器支持，但我不确定 AD7768 是否支持 DCMI。）如果 AD7768 也支持，我想知道 PCB 应该如何正确布线。Translation to English I am trying to communicate with the AD7768 using the STM32L4R9, using 8 channels. What ...
STPM34 DC offsets failed to be measured after all HPFs were disabled.
Hi, We try to use STPM34 to measure DC power besides measuring AC power. We had to disable the HPFs of V1,V2/C1,C2 on the EVALSTPM34 board by sending {0x00, 0x01, 0x18, 0x04, 0x88} and {0x02, 0x03, 0x18, 0x24, 0x92} to STPM34 through SPI. When we...
STPM34 (EVALSTPM34) - After HPF is disabled, why did we failed to read the V-I channel's DC offset of V / C channels?
Hi, We try to use STPM34 to measure DC V and I inputs besides measuring AC. The HPFs of V1,V2/C1,C2 on the EVALSTPM34 board were disabled by sending {0x00, 0x01, 0x18, 0x04, 0x88} and {0x02, 0x03, 0x18, 0x24, 0x92} to STPM34 through SPI. ...
