STM32F103RCT freeze on readAllRegs(); RFM69HCW [SOLVED: use Serial1]

[martin321]

Hi

I have a STM32F103RCT and RFM69HCW running stm32duino.
There is another SPI ic, this CS pin is set high.

CS is on PA4
IRQ on PA3

I can read temp when uploading modified Gateway firmware without SPIFlash and sending 't' over serial.
It freezes when trying to send 'r' to dump all registers.

Have tried to get this to work but can't seem to figure out what is wrong.

This is a dump of registers not using library.
Looks like all have the default value except 0x0B(AFC control in low modulation index situations), this is 0x40 instead of 0x00

Hi,

found out that the Serial.print lines in library needed to be Serial1.print
Now just need to find a way to change to Serial1 when card is setup to use this.
