From fe9bd0afb9a45dbad9ca06bd496e2cf72a080dac Mon Sep 17 00:00:00 2001 From: Sergey Vlasov Date: Mon, 19 Apr 2021 10:32:14 +0300 Subject: [PATCH] Fix F303 audio output on A4 with the dac_basic driver (#12480) The dac_basic driver did not work properly with `#define AUDIO_PIN A4` (instead of configuring the A4 pin, the driver actually was switching the A5 pin to analog mode, breaking any other usage of that pin in addition to emitting a distorted signal on the improperly configured A4 pin). Fix the code to configure the A4 pin as intended. --- quantum/audio/driver_chibios_dac_basic.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/quantum/audio/driver_chibios_dac_basic.c b/quantum/audio/driver_chibios_dac_basic.c index b8cec5ff1..fac651350 100644 --- a/quantum/audio/driver_chibios_dac_basic.c +++ b/quantum/audio/driver_chibios_dac_basic.c @@ -101,7 +101,7 @@ static const DACConversionGroup dac_conv_grp_ch2 = {.num_channels = 1U, .trigger void channel_1_start(void) { gptStart(&GPTD6, &gpt6cfg1); gptStartContinuous(&GPTD6, 2U); - palSetPadMode(GPIOA, 5, PAL_MODE_INPUT_ANALOG); + palSetPadMode(GPIOA, 4, PAL_MODE_INPUT_ANALOG); } void channel_1_stop(void) {
