Hi I am trying to write a code using STM32f103r8t6, i have installed IAR for Arm v8.40.1 i started to create a project but i could not find any library files. and then by downloading an example file i got the library files as i tried to complile i m ...
I detected that ART accelerator and prefetch is not enabled. Why for loop gets slower if if I switch both on ? /* USER CODE BEGIN SysInit */ #if defined(FLASH_ART_ON) // enable ART for Flash (x8 Booster) int FLASH_ACR_REG=0; volatile unsign...
Hi!I have a basic code - blinking LED code which uses onboard LED (PC13). The problem is that it doesn't toggle at all, it just stay switched on and doesn't go off after delay. I've tested that code in debug mode and everything worked fine, it toggl...
CPU 210MHzIf you run IRQ code from flash you have about 5 times more cpu cycles as needed (7WS)if you switch on ART accelerater and prefetch: for loop gets slower no influence on IRQ latencyyou could not run code from internal SRAM because of missin...
Hi folks, I have tried to run my complete program out of internal SRAM to speed up the IRQsbut if I come to svc 0 it failsprvPortStartFirstTask: 20005ee0: ldr r0, [pc, #32] ; (0x20005f04) 20005ee2: ldr r0, [r0, #0] 20005ee4: ldr r...
We are using STM32F765IIK6 176 pin 10x10 0.6mm UFBGA, die rev "Z". Whilst processing these through SMT solder reflow (using an 8 zone forced air convection oven) we had a number of these devices failing, due to the substrate of the BGA package dishin...
Hi,Does anyone know if there are any companies out there that sell production ready stm32 hardware boards. I appreciated there would be a lot of variations regarding io etc.. but i just wondered if it was a "thing" or if the only board are typically ...
I'm trying to enter STOP2 mode to save energy but the MCU get stuck in the function HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI). I have cleared all EXTI pending flags and RTC flags, and disable all five wake up pins. The MCU is supposed to wake up vi...
I use STM32F102 and TIM2 timer in PWM1 mode to generate defined frequency and duty cyclesquare wave. I have some questions and I hope can get some help from experienced colleagues.1. I update the ARR/CCR1 register in an interrput which is defined by ...
I have done some investigation and arrived that the problem is with the "DIR" bit in the Interrupt Status register not firing to indicate whether to do a Read.uint32_t isr_trace[64]; int isr_count = 0; void I2C2_EV_IRQHandler(void) { isr_trace[...
