as with the stlink mods your limited to a 5v out at 200ma and if the usb was broke out i could use a usb c connector on a pcb and have alot more voltage options

im using pc8 as a reset pin and ive check it with a logic analyzer and wen its initalized it drops low then goes back to high before im calling my function to drop it low btw im using saleae logic 2 void reset_pin_init(void){ //PC8 RCC->AHB1ENR |= ...

so i put a bigger decoupling cap on the vdd vss for the mcu and it works now and i noticed that you have to clear bit 18 before setting bit 16 in the RCC->CR

the stlink v3 mods is really great but i wish they would make a version without the usb connector soldered on and break out the usb input

here is a reference design for a voltage translator circuit from st and if you look at the jtag section on page 3 it is used as a direction controlhttps://www.st.com/resource/en/hw_model/stlink-v3mods_voltage-translator_reference-design.pdf

thanks i changed the code to thisvoid reset_pin_init(void){ //PC8 RCC->AHB1ENR |= (1U<<2); GPIOC->ODR |= (1U<<8); GPIOC->MODER &= ~(1U<<17); GPIOC->MODER |= (1U<<16); GPIOC->OSPEEDR |= (1U<<17); GPIOC->OSPEEDR |= (1U<<16); GPIOC->PUP...

STM32C011J4M6 trying to use HSE as clock

i couldnt figure out how to post to ideas but i would love if st would make a version of the st link v3-mods that didnt have to usb connector on it and break out the usb input for programming
