Hi againI'm using STMG071 with 2*DAC. I need them as negative inputs to COMPx.in order to use PA4/PA5 for other purposes – I set DAC1->MCR =0x00030003; so DAC will not be output to the pin (PA4/PA5).Yet – as soon as DACs are enabled (DAC1->CR 0...

Hi allI need to write an external programmer for STM32G030J6.I've written the SWD protocol, and I'm able to program all FLASH (if no protection applied).the issue is: I can’t write to the FLASH OPTION: (changing protection level from 1 to 0) I can’t ...

my init: I2C1->TIMINGR= 0xB0420F13; //p942 p917 XTAL=48MHZI2C1->MY_I2C->TIMEOUTR= 0x0000900A; //p943I2C1->CR1=1; no irq are involved (yet)then I'm trying to start a frame (slave not connected- still- I would like I2C to send 1st byte)I2C1->CR2=...

HiI'm developing on STM32G071C8 with the developing circuitI'm trying to reach 64Mhz as system clockI'm programing RCC->PLLCFGR as follows:R=Q=2 (both on) . P=off N=16 M=2 or N=8 M=1 PLL source=HSI16any combination above 54Mhz - disconnects Flas...

news:allthough I cant make PA5/PA4 output: they work fine as digital input && ADC input

I’m waiting (41mS).mass erase is a desired outcomefor me. Can’t even change FLASH->OPTR under a standard debugger. Yona

Ive changed all:pin configuration,enabled I2C2 pwr,clock, all refernce to I2C1-> changed to I2C2->I dont mind helping ST to analyze my problem: maby it realy is a bug in the micro (?)after all: this isnt my 1st question in this forum- and they were ...

so... tryed to use I2C2: works there !!!!this means that I2C1 just might contain a bug ? (hard for me to believe)should I report this issue to ST for them to check it further ?nothing to do with desperation: though I would rather not get stuck in so...

Im working with 48Mhz. everything else works (GPIO,UART,TIMERS...). also the baud of the SCL is fine and Ive init I2C1->TIMINGR acording to the table (48Mhz=> 100Khz I2C) . this does result to a 100Khz baudIve swaped circuits thinking the problem mi...

DAC OUTPUT

I cant write to the FLASH OPTION register

Hi I have a problem with I2C: I cant make it send 1st byte(addr) properly (10%-20% of the time)

Hi I'm using a STM32G030F6. I cant find how to remap the IO ports to the pins: example: Pin1= PB7 /PB8 ? Pin20= PB3/PB4/PB5/PB6 ? register SYSCFG_CFGR1 only selects PA9/PA11 && PA10/PA12 thanks Yona
