Hi ,We are seeing STM32F051K6 have a drift of 7 milli seconds per 1 hour running on HSE . Time drift of 7milli seconds for 1 hours is 1.944 Parts Per Million ( 7000 micro seconds / 3,600,000,000 Micro seconds = 0.000,001,944 )The OSCILLATOR has ± 10 ...
My problem is i require emulate with STM I2C chip , that requires wake adr send before comm. But normal slave code isnt handle this.Signals on bus (FYI master is other device no STM)as can see master send one adr without data and repeat, first reply ...
Hi,I ordered a PCB and after I had soldered all the components I noticed that in the PCB there was a connection between my SWD interface to I2C pins (PF0, PF1) and SWD pins were connected to the I2C bus. I tried short-circuiting them with a tiny copp...
Hi. I'm using STM32F030C8T6 MCU to communicate with multiple DS18B20. I'm using Timers to make 1us delay. I set my prescaler to 48-1. and I'm running on 48MHz clock. when i connect two sensors to my MCU, i can't read temperature, so for testing i dis...
I am trying to make a pwm signal ,with Lookup table for duty cyle .Here using TIM1 of stm32nucleoF070.I am here using DMA ,reffered a lot of from google and just worte as follows No variying singal is getting SystemClock_Config(); /* USER CODE BE...
I have a custom board that I need update by USB. I have a jumper that allows setting the following:nboot bit set to 1BOOT_0 pin set to 1. Then I power on the board and I can see the stm32 bootloader device on my windows machine. First I get a similar...
Hello experts I am trying to make a PWM signal from DMA , with PWM + complimentory channelWhen i use HAL APIHAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sin_table, 32);// Here I get the signal as expected But when I Use HAL APIHAL_TIMEx_P...
Hi I am using STM32F401RE controller but on my PCB, so here can I use the pins allocated for its programming/code dumping also as normal GPIO's. Any precautions which needs to be taken care of?
What is the best meathd to of feedback method In sineinverter (like commercial) ?is it good by a forumal appling instead using look up rable .It saves the memoryIf i use look up tableconst unsigned char sin_table[416]={0, 16, 32, 47, 62, 77, 91, 103,...
Hi All,I'm starting to get familiar with the STM32 Series of Microprocessors and I'm completing some exercises using a mixture of direct writting to peripherals and low level ST libraries using the CUBEMX to get familiar with the chips. I'm using the...
