I have an STM32F103 (blue pill) connected to an NRF24L01. I have the interrupt from the NRF triggering an external interrupt, and I'm reading 16 bytes in to the STM32 using polling. All of that works dandy, but I would very much like to interrupt, ...
Posted on January 31, 2016 at 22:24I'm working my way through AN4061:http://www.st.com/web/en/resource/technical/document/application_note/DM00049914.pdfUnder section 2.3, it says ''This section describes the driver implemented for the EEPROM emulat...
Posted on August 22, 2015 at 16:10I was developing a system on the Nucleo board. I then moved it to a custom proto PCB which I was programming from the Nucleo on-board ST Link. Everything was great up to that point. When I reverted back to use the...

I'm using the Cube code generator to try and duplicate the Cube example project of generating an interrupt and toggling the user LED on a Nucleo L053R8 board. The example in the Cube package works fine, but trying...

I am using Cube generated code, exported to EWARM, running on a Nucleo L053R8 board. My question is how to select the active ADC source outside of the ADC initialization code. For instance, with channel 12 and 13...
gbm, thank you, you have been a great help. That's some pretty non-intuitive stuff right there, the two DRs at the same address, one read and one write. I see it now on page 746: "The data register is split into 2 buffers - one for writing (Transm...
Ok, that helps a lot, thank you. So your LIS_SPI_RX_DMACH is the receive channel (or stream depending on which device), and the LIS_SPI_TX_DMACH is the transmit channel/stream. Then you call LIS35_Get_position_DMA and it will automatically transmit...
Yes, I do have SPI set up and functioning properly using polling. I can interact with all the registers on the NRF24L01, and do a burst read of a full payload of 32 bytes. Are you saying do the DMA configuration, then send a dummy byte? I tried th...
Posted on January 31, 2016 at 22:52Ok, got it. Kinda confusing when in the app note they call it ''the STM32F0xx Flash memory driver'', but on the web page under ''Sample and Buy'', you download ''STSW-STM32117'' and that is what they were really r...
Posted on August 23, 2015 at 16:54Yes, I disconnected the other board and it is a stand-alone Nucleo now, with the ST-Link jumpers reinstalled. I have tried computer restarts, restarting IAR, unplugging/plugging it back in etc. It just will not pr...
