Re: Can't program F401 after PA9 set as INPUT_PULLUP
I suppose you are using a stm32f401cxx blackpill (or some such variant?) https://stm32-base.org/boards/STM32F401CCU6-WeAct-Black-Pill-V1.2.html the 'usual' thing is, keep your usb cable connected press both boot0 and reset hold boot0 and release reset release boot0 1-2 secs later you can check in 'd...

Re: Generic_F030RCT missing?
Binary size difference appears to be Newlib Standard vs Newlib nano setting... Not entirely sure what newlib is... :D Clock situation still appears to be happening. I once tried things like -nostdlib -nostartfiles -nodefaultlibs https://gcc.gnu.org/onlinedocs/gcc-4.4.2/gcc/Link-Options.html and the...

Re: Hardware Serial returning gibberish.
many GPS device initialize at 9600 baud, not 57600 baud. and various of them offer commands to set the baud rates after initially connecting at 9600 bps if you do not know the actual GPS bauds, to avoid getting gibberish, you would need to practically test every practical known baud, till one that d...

Re: strange USART behaviour
for uart, your *baud rates* and line discipline (e.g. 8N1) matters. for usb (CDC) serial, it doesn't matter, there is no baud rates, it is straight 12 Mbps USB full speeds based on the specs. so if you are using uart and the other side is not at the same baud rates, all data will be garbled. for uar...

Re: ToneAC on stm32
you can try playing with the hardware timer and PWM https://github.com/stm32duino/Arduino_Core_STM32/wiki/HardwareTimer-library https://github.com/stm32duino/STM32Examples/tree/main/examples/Peripherals/HardwareTimer but that if that is some form of sigma delta DAC https://en.wikipedia.org/wiki/Delt...

Re: STM32SD adjust file timestamps?
apparently STM32SD https://github.com/stm32duino/STM32SD depends on FatFs https://github.com/stm32duino/FatFs which has a getfattime() callback https://github.com/stm32duino/FatFs/blob/bf405bad29c66accd9df5570084ad80a8c78cd11/src/ff.h#L295 https://github.com/stm32duino/FatFs/blob/bf405bad29c66accd9d...

Re: I2C communication does not work.
I2C requires a 'different skillset' vs playing with uart, uart is point to point, it is only 2 devices a sender and the other a receiver and vice versa. but of course it is up to one to make things complicated by adding RS485, RS422 etc, but that is off-topic. Then that for i2c, many devices share t...

Re: I2C communication does not work.
that device has uart
https://en.gassensor.com.cn/Product_fil ... cation.pdf
have you tried that?
uart just take different pins and is normally accessible at Serial1, Serial2 etc.
