'Adafruit_MAX31865(7, 4, 5, 6);'
Why?
'Adafruit_MAX31865(4,7,6,5);'
Why? 7,4,5,6?

I'm curious.

No matter how hard I try, it doesn't work.
Can someone help me?

Even if I use 'Adafruit_MAX31865(7, 4, 5, 6)', the exact value does not come out.
It seems to be a problem with the library code.

Adafruit_MAX31865 thermo = Adafruit_MAX31865(7, 4, 5, 6);

It seems that SPI communication is working, but the actual result value is not correct.
I am looking for another library.

14:43:45.948 -> REFIN- < 0.85 x Bias - FORCE- open
14:43:45.948 -> RTDIN- < 0.85 x Bias - FORCE- open

I want to know how to turn off 'watchdog' on STM32F103C8T6.

For example, in the case of Arduino,
wdt_enable(WDTO_4S); ON
wdt_disable(); OFF

(maple board)
core : https://github.com/rogerclarkmelbourne/Arduino_STM32

iwdg_prescaler WATCHDOG;
uint16_t TIMES = 10000; // 65,535
iwdg_init(IWDG_PRE ...

Thank you for your reply.

Is there a way to use 4 STM32F103C8T6 UARTs (TTL)?

Is there any way to use 4 'UART' functions?
Either hardware or software.

hello. Nice to meet you.
MCU: STM32Duino STM32F103C8

1. The operation was implemented through the ‘u8x8’ library.
2. However, the 'setContrast' command of 'u8x8' is not ...
