1. Can you tell us why this RTC reset happens only in the negative temperature? 2.Also,during battery powered ON condition,does the leakage current Loads through RTC supply(VCC) causing a voltage Dip in the battery voltage?
Dear Sir/madam,We are using Serial RTC chip(M41T93ZMY6F) in one of our application. In the datasheet,it is given as the RTC chip can be operated in the range of -40 deg C to +85 deg C.During Low temperature (-10 deg C), vacuum condition (5*10^-5 bar)...
documentation errors in RM0444
Offset values shown in Table 84 are out of range according to Table 1.Also, "Address offset" of each COMP registers is different from the table.Section 10.1 says that the assignment of DMAMUX request multiplexer outputs to DMA controller channels is ...
Power current consumption in low power mode in STM32L0 is higher than as compared to the datasheet values.
Hi,I am using an STM32L010 and want to operate it in low power mode. The way the firmware works is I start the LPTIM2 with interrupt every 1 second and then go back to sleep once ISR is serviced. Right now the ISR just has a variable that acts a coun...
Resolved! fix STM32f103 __WFI function gives hardfault_handler
Hello,I enter stop mode using HAL_PWR_EnterSTOPMode and the processor come out of this function immediately and does not wait for any external interrupt. can someone help me on this?
I want to use CubeMX examples with CubeIde
I just started using CubeIde but using Cube examples gives a lot errors. Should I just copy all the .H and .C files (from where?) somewhere or is there a better way.I have 32H750 and 32F746 Discovery boards and my own boards.
Resolved! UART transmit DMA not working (bare metal, no HAL)
Hello,I am trying to get the UART to transmit some bytes with DMA. Nothing happens. RCC->APB2ENR |= (uint32_t)((1<<14)|(1<<2)); // Bit 14 USART1 clock enable & Bit 2 I/O port A clock enable GPIOA->BRR = (1<<10); // pull-down PA.10 GPIOA->...
How to build a library using Keil for the project using Cube
Let's say I want this function to be within my library:// library function float mili ( unsigned x) { return x/1000.0 } // main function int main (void) { float volatile tt; unsigned t; for (;;) { t = HAL_GetTick(); while (...
