cannot compile: SPI.transfer() SPI...setMosi missing

[tueddy]

Hi,

very interesting project! I want to upgrade firmware for lower power card detection (LPCD)
But i'm unable to compile. I have installed the bluepill support from this tutorial:
https://www.heise.de/developer/artikel/Keine-bittere-Pille-die-Blue-Pill-mit-ARM-Cortex-M3-4009580.html
Blink demo works fine after installing.

On compiling your firmware-updater i get several errors SPI things are undefined:
void PN5180_Firmware::Begin() {
SPI.setMOSI(MosiPin);
SPI.setMISO(MisoPin);
SPI.setSCLK(SckPin);

and
SPI.transfer((uint8_t*)TxBuffer, TxSize);

What is the exact environment to make this work? PN5180 wiring seems fine.
I've also tried to compile using ESP8266/ESP32 but get guru mediation errors, maybe progmem?. Arduino UNO has not enough ram. Any ideas how to get this working?
Best

I finally managed to update the PN5180 firmware to version 4.0 using the official st-libraries and the st-link V2 programmer. the SPI library described in tutorial above seems incompatible.

Thank's for your great library!

I finally managed to update the PN5180 firmware to version 4.1 using ESP32, no additional hardware or anything needed. Arduino development environment was used.

After extensively raking through zGrEaNz's code I found minor(but crucial) programming issues. Although these issues may just be specific to ESP32 board. The guru mediation error occurred because ChunkCounter variable was not initialized. Also no number was passed to MaxChunkSize when SecureDownloadTransceive() was called in lie 529 of PN5180_Firmware.cpp.
