* Fixed UART overrun error * Added stability test scripts * Refactored UART code. ESP/GPS now uses DMA in circular mode to directly write into the ring buffer, saving a bunch of interrupts and potential race conditions. * Changed stability test to use amount of bytes instead of amount of non-zero messages, since the ring buffer pointer is only updated on half or full DMA transfer or on line idle (e.g. no more 1 char messages from the gps) * Increase data limit. It's too low sometimes in normal operation * Forgot to set write pointer in ring buffer * Increased test limit even more |

This is the firmware for the comma pedal. It borrows a lot from panda. The comma pedal is a gas pedal interceptor for Honda/Acura. It allows you to "virtually" press the pedal. This is the open source software. Note that it is not ready to use yet. == Test Plan == * Startup ** Confirm STATE_FAULT_STARTUP * Timeout ** Send value ** Confirm value is output ** Stop sending messages ** Confirm value is passthru after 100ms ** Confirm STATE_FAULT_TIMEOUT * Random values ** Send random 6 byte messages ** Confirm random values cause passthru ** Confirm STATE_FAULT_BAD_CHECKSUM * Same message lockout ** Send same message repeated ** Confirm timeout behavior * Don't set enable ** Confirm no output * Set enable and values ** Confirm output
