HiIn your Reference Manual for the STM32F469 at 31.3.11 it says:A DMA access is requested when the TXE or RXNE enable bit in the SPIx_CR2 register is set.But the SPIx_CR2 Register does not have a TXE/RXNE bit, it has a TXEIE/RXNEIE bit which just en-...
I need to calibrate the internal timer to do ADC sampling using GPS receiver.The accuracy of measurement is most important (zero or minimum jitter), PPS output of GPS receiver is input.Thanks in advance
I have created a simple project, where I need to get the interrupt at exactly 1us.Please find attached an image of the clock configurations that were created in STM32Cub3MX.I am using TIM3 which is associated with APB1, so the MAX frequency for this ...
Hi,I am using STM32L4S5ZI which has only a timer with maximum capacity of 32-bit. The DWT(Data Watchpoint Trigger) is somehow not available because when I check for DWT->CNT it always shows 0. So I needed a 64-bit timer for my application which keeps...
Hello everyone;I'm working LUPART with STM32H747. I have a problem like this;- LPUART 1000000 baudRate has been installed. LSE clock is not used.There is no problem when the LPUART's RX-TX line is physically connected to the module. But when I physic...
HiI just wonder at the example:STM32Cube_FW_F4_V1.26.0/Projects/STM32469I-Discovery/Examples/FMC/FMC_SDRAM/Src/main.cand there is a define:#define WRITE_READ_ADDR ((uint32_t)0x0800)Whats the purpose of that (offset?)? Doesn't the FMC SDRAM start ...
Hi Experts,I need to run my code (it is a small code) from internal RAM. It currently runs from the first sector in the flash. For some reason, I need to change a few bytes in the same sector and it seems I can't write to the same sector from where t...
I am trying to work on an acoustic system but unfortunately the system is not responding as it should and i have connected all the equipment.Kindly see attached for reference.Thank you.
Hi all,I'm trying to manage a long pression on a Flex button.I want realize this simple algorithm:short pression = action_1()long pression(IE 2secons) = action_2()I enabled clickListener over this Flex button, I configured the trigger event on "Touch...
AN4221 says it will enter I2C boot mode on detecting its address and will then start waiting for commands. What is not clear is whether this address is sent as part of the first command, or by some separate undescribed operation. I've tried various a...
