Resolved! Failed to erase / program flash memory - read out protection
Posted on June 13, 2017 at 09:15STM32L053 Nucleo Board.I am trying to program or erase board using ST-LINK_CLI.exe (Ver 1.3.0) / STM32-LINK Utility (Ver 2.3.0) but I get error message saying 'Read out protection is activated' I am not able to erase ...
[Solved] PWM TIM1 output randomly dropping out when modulating the frequency
Solution: the ARPE bit was not set in the CR1. TIM1->CR1 |= 0x0080; solved the problem.Dear community,I am experiencing with an issue using TIM1 as a PWM timer. It all works fine, I can set the frequency and duty cycle with TIM1->ARR and TIM1->CCR1. ...
Seeking STM processor that has wide mux feed the pga-OpAmp then feed ADC
Have found great info on very flexible op amp with pga ability. The STM32H7 - OpAmp presentaion for example. Have found great info on ADC subsystem in the STM32H7 - ADC presentaion and in datasheets for specific STM32H7 part(s).Have seen the very w...
N-pulse waveform generation application example - part2 (AN4776)
Hi .I have problem with this back to back timer configuration . (in AN4776)What I get :1- Timer 1 is making PWM ( i just need a regular pwm but this examle is a complementary one )2-Timer 1 will send a trigger to timer2( which is it's controller acut...
STM32G474 ADC Master-Slave
I am slightly confused with the ADC Master - Slave configuration. Maybe someone can shed a bit of light in here.Using a STM32G474RET (LQFP64), thinking of chaining ADC1 and 2 in a master/slave configuration. Looking at the attached schematic, PB1 and...
Resolved! STM32F446 synced timers with phase shift
Hello,I'm using a Nucleo F446ZE to test timer capabilities to make a peak-and-hold PWM driver. I already have the core functionality where TIM1 uses DMA to run through a buffer of variable duty cycles at a higher frequency (e.g. 5 kHz) for the high-s...
STM32L475 LSE crystal oscillator doesn't tune correctly - gmCrit value on datasheet is very low
Please help if you can, but please do me the courtesy of reading in full before replying: We have a product using STM32L475 with a 32768Hz clock on the LSE. When I attempt to tune the crystal oscillator to within the performance spec of the crystal ....
HAL_I2C_ErrorCallback is called when I use HAL_I2C_AddrCallback
Hi,I am trying to emulate a EEPROM with my STM32F103 as a I2C slave. I'm using STM32CubeIDE 1.0.2.The chip that will request data doesn't write data to the EEPROM, so I can use only an array to save the data in the code. And it cant have any code in ...
