1. Is it ok to set 3.3V as a divider output which goes to ADC pin?2. The external voltage at VDDA pin (We have given the same VDD as VDDA) show some fluctuations while ADC monitoring so can you suggest the best possible way to monitor battery voltage...
Dear community,I am using the STM32F103C8T6 32 bit ARM Cortex M3 microcontroller.In Section 9.2.1 in the reference manual (GPIOx Control Register Low) it says that the reset value is 0x4444 4444 (which means all pins are floating inputs).However, whe...
Hello everybody!I try to configure TIM2 to interrupt in the range of 100Hz ... 1kHz. Strangely, the actual frequency I set is divided by 2: if I configure the timer to run at 1000Hz, it will run at 500HzTIM2 configuration:void System::InitTimers() ...
Looking at the datasheet for STM32F20xxx ADC; if I run the ADC at 30MHz and use the minimum sample time of 3 (100ns), the input sample capacitor will not be fully charged even with zero source resistance. The input spec is 6K and 4pF, if you take th...
I've got a real strange error, and I really don't understand it. I'm using a STM32F407VET6 Microcontroller. I also use CubeMX to generate the configurations. But especially with the Timers, it's not possible to set every setting I need with Cube, so ...
STM32F303 SPI hardware auto NSS can't work on CPHA = 1 ?Why?
I'm a tiro of ST-LINK/V2 and STM32 tools.Recently, when I upload a file via ST-LINK/V2 to my STM32 tools (OpenIMUZA300), the upload prosess was failed.The warning messages are:no flash bank found for address 0x10020000no flash bank found for address ...
Dear Members,I tried to talk with SIM7600 using UART1,The code was working ok with SIM900,Now,it's giving me the result but it's not right,Is it because of baudrate ? it was 19200 for SIM900and now 115200 for SIM7600the code :void test_modem (void) {...
hello i need to protect my code from reading or just protect the two first pages is enough because ill put my devices on market ? i cliked on execute only code option in keil flash options my code doesnt compile here is the error :..\Middlewares\Thi...
