Arduino for STM32

As it turns out, the Bluepill SPI interface appears to be much more robust than that of the F303RE. It was not a crash per-se but severe data corruption that appeared to halt the program. The wire length used on my test-setup for the BP was, apparently, too long for use on the F303RE. Shortening up ...

Using mlundin 's method I was able to determine the following:

According to the CFGR section of: https://www.st.com/resource/en/reference_manual/dm00043574-stm32f303xb-c-d-e-stm32f303x6-8-stm32f328x8-stm32f358xc-stm32f398xe-advanced-arm-based-mcus-stmicroelectronics.pdf

I have modified my Nucleo64 (F303RE) board to utilize an external CMOS oscillator though pin29, per the Nucleo64 datasheets. It appears to be working but as the remainder of my project relies on this external oscillator is there a method of determining if the HSE clock is being utilized or if it has ...

Thanks for the response,

No, there are no other devices on the board. D13 is shared with the onboard LED (LD2) but this isn't causing a voltage issue on the pin (I have measured this), and with a ~500R resistor, its current draw (~3ma) should not be saturating the pin.

To my knowledge there is ...

Hello,

I am trying to interface a W5500 ethernet PHY with the F303RE and am running into a great deal of difficulty. The SPI interface seems to go crazy after udp endpacket() command which appears like a hung/crashed state. Prior to the crashed state, there is data corruption in the values returned ...

Thanks for the response... but I don't know what to say. It is. the serial.println I have at the top of the loop stops publishing. I have to take that as either the system has crashed or something is blocking. I will stick the pin on the scope in a minute to see what that pin is doing.

Same result, I have tried them both.

Hello,

I am having the problem where attempting to use the w5500 ethernet module with a Nucleo STM32F303RE results in a hang/crash on the udp.endPacket command.

I am using the Ethernet library provided in the Arduino IDE. I have had this working working with a Bluepill in the past. I have searched ...
