Part Number: AFE782H1 Hi,
I tried to disable the CRC for communication with AFE782H1. The very first command I sent was
u8 dis_crc[4] = {0x02, 0x00, 0x26, 0x24} ;
followed by a two NOP commands
static u8 nop_cmd[4] = {0x00, 0x00, 0x00};…

We are planning to use AFE782H1 for 4-20mA and HART requirements. We don't see any good material on frame format for SPI (DAC) and UART (HART) communication with AFE782H1…
Part Number: AFE782H1 Tool/software:
In AFE782H1 Evaluation board circuit the HART Output from the IC going through C12,R14 forming LPF whose Cutoff frequency is 338.7Hz but HART signal frequency is 1200hz to 2200hz then signal will attenuates.

Part Number: AFE782H1 Hi,
We have setup AFE782H1 for DAC + HART using SPI communication. The responses from the MCU are sent to HART Modem when sniffed on a serial port looks like a part of previous response is sent along with the current response data…
Part Number: AFE782H1 Other Parts Discussed in Thread: AFE882H1 Tool/software: Hi,
We are using AFE782H1 IC in that Vref utilizing for op amp input.But the Vref has to be constant 1.25V but it is increasing to 1.26,1.27,1.28 randomly.
what might cause…
