Posted on March 29, 2014 at 15:32I have some IoT application, where power gets quite critical. Comparing the current/MHz of different suppliers, I found the best STM32 in the STM32L0 line at about 80uA/MHz. Atmel proposes a pico-line with 70uA/MHz (...
Posted on March 29, 2014 at 09:18I am using DMA to transfer ADC data to a uint16 variable @ 1MS/s Than the value is shifted with another DMA channel to SPI and sent to an external DAC. Unfortunately the external 14 bit ADC does not allow for left a...
Posted on March 29, 2014 at 00:40Is anyone aware of any documentation that contains an easily parseable system register specification for an STM32 MCU that one could use to generate code, documentation, etc... from? Something like the reference man...
Posted on March 28, 2014 at 16:42I want to generate sine wave (single cycle) and then change the frequency using DAC. basically Sweep the frequency... How would I do that.Thanks for your help in advance. #stm32f4
Posted on March 26, 2014 at 11:26In the user manual: AN2606 - STM32 microcontroller system memory boot mode it describes that when using a 14.7456MHz clock crystal the bootloader configures the PLL to run at 48MHz. How is this achieved? What setting...
Posted on March 28, 2014 at 11:46Hello all,I am trying to connect a sensor to the stm32f4 discovery board. what i want to do, i want to be able to write to the sensor and read from the sensor the data. would you please guide me to any web resources...
Posted on March 18, 2014 at 16:34I've the problem that STM Studio is not able to import arrays (fixed size) of variables. That is, they are not in the list based on the imported elf file. Array of bytes are not a problem but arrays of all other typ...
Posted on March 25, 2014 at 21:49Hello, i want to ask something about embedded operational amplifiers in stm32f3. Even when my application is not running, i am feeding an external signal to the op amp through I/O pin. When i start my program, i see ...
Posted on July 20, 2011 at 14:12Hello, in my application I use a part of the flash (0x8007C00 ... 0x8008000) as memory for my own data. I's all ok when I locate the application at address 0x8000000, but when I locate my application to address 0x8003...
Posted on March 27, 2014 at 16:23HelloMy STM32F103RBT6 has problem with PWM output (TIM2 CH4) as servo control.This problem only occuring while USART2 is processing interrupts because of received data.Interestingly, there is also some parallel with ...
