Other Parts Discussed in Thread: MSP430F2370
Hi,
We are using sloa214 Application code as base code for our boar with MSP430F2370 TRF7970A and our board is similar to TRF7970A EVM in terms of GPIO assignment.
In case of SDM trasmission in Auth1 MSP430F2370 should be sending 4 byte.
0x60 , 0x04, CRC_1, CRC_2
so it should be below binary form with parity bit for first 2 byte
000001101 001000000
but when RFID card Auth fails on logic analyzer we are observing following data. It is geting shifted to the right.
0000001101 001000000
See attached waveform or open attached Logicport session (can be viewed in https://www.pctestinstruments.com/downloads.htm) for more detail.
On same board some time cards works perfectly fine with reduced range. what could be possible reason. LogicPort_MSP430F2370_TRF7970A.rar
