STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
I use the BSP functions to record audio. The sampling frequency is set to 8000 Hz and the buffer size to save the recorded data into is set at 8000 elements long. It would make sense if the time to fill up the buffer is 1s. However it takes exactly 5...
I have been using Atollic TrueSTUDIO for STM32F3DISCOVERY applications to write and test algorithm for a client. After successful debugging and testing I have to handover the project to the client. However I cannot reveal my source code which is actu...
In the STM32l476, I have found that the VREFBUF_CSRregister 'HIZ' bit is being set from default 0 to 1 when SET_BIT(RCC->APB2ENR, RCC_APB2ENR_SYSCFGEN) is executed. RCC_APB2ENR_SYSCFGEN is the LSB.
I bought Discovery kit for LoRaWAN™, Sigfox™, and LPWAN protocols with STM32L0 . Then I read https://github.com/aureleq/muRataSigfox . This is about my same kit. I was able to register it with Sigfox. More, I read http://blog.aha.nl/2018/02/getting-...
Hi,Our device sometimes turns on from Standby by itself. The only wakeup sources enabled are a couple of wakeup pins.I saw the device reset (from standby) by itself, and the PINRSTF flags in RCC->CSR was set. The reset pin has 100nF capacitor to Gnd ...
Hello,I have been using STM studio for monitoring run time behavior of a software for STM32F4 and I have noticed that traces of some variables contain abrupt changes to zero value. The zero values are displayed despite the fact that the actual value ...
Added ADC interrupt handlers to my code.But Overrun interrupt will not compile
Posted on June 23, 2017 at 14:04Hi!Currently I'm using lwip + tinymDNS on a stm32f207.The mDNS needs multicast packets. I activated IGMP in the lwip stack and it works.mDNS messages were sent as mutlicast packets.But the one thing that did not work ...
Posted on March 15, 2017 at 02:47I have just started experimenting with ST products. I have a STM32F4 Discovery board. I bought a DP83848 PHY on Ebay and connected it to the Discovery board. I downloaded a hex file from here:[https://community.st.co...
I trying to use STM32H743VI DMA1 to read from SPI2 MISO RXDR in master mode. Allocated memory in the D2 domain at address 0x3000000C for the DMA1 to copy SPI2 RXDR register to, but the resulting data is corrupted. I did not enable any D-cache at leas...
