2017-10-11 | Cleanup 'unused parameter' warnings, a couple of which are actual coding errors. | Paul Selkirk | |
2017-08-31 | Withdraw SysTick_hook (commit 9ffead1), because it turns out there was ↵ | Paul Selkirk | |
already a user-callback mechanism with HAL_SYSTICK_IRQHandler() and HAL_SYSTICK_Callback(). | |||
2017-07-31 | Add a generic SysTick hook, to call a function on every 1ms tick, because ↵ | Paul Selkirk | |
it's easier than setting up a dedicated timer. | |||
2017-04-29 | Remove exception handlders that I probably shouldn't have defined in the ↵ | Paul Selkirk | |
first place. | |||
2017-04-01 | Change RPC UART to have a high-priority thread monitoring a large(ish) DMA | Paul Selkirk | |
buffer, because we've observed out-of-order receives under load. | |||
2016-09-20 | Still some problem with uart receive under heavy load, so change to a 2-byte ↵ | Paul Selkirk | |
receive buffer with half-complete callbacks, and raise the dma priority. | |||
2016-06-13 | Only the HSM project needs the RTOS; most of the test projects can use the ↵ | Paul Selkirk | |
STM32 HAL code directly. | |||
2016-06-07 | fix some comments | Fredrik Thulin | |
2016-06-06 | Split HAL_UART_RxCpltCallback into uart-specific callbacks. | Paul Selkirk | |
2016-06-02 | Use DMA for UART RX instead of interrupts. | Fredrik Thulin | |
DMA is more efficient and less prone to miss characters than interrupts. An open question is if circular mode is really the best. If someone copy-pastes more than the RX buffer size of configuration into the CLI, we risk the DMA controller catching up with the reader and overwriting data not yet read. Since we don't have flow control back to the users terminal, we will always fail if too much data is entered before we can process it. The question is if failing to stuff new data at the end of a buffer might be better than data being overwritten - thus messing up the commands in unpredictable ways. | |||
