From 364aeeec53b56efae45594940f1b634e7f16d69c Mon Sep 17 00:00:00 2001 From: Don Armstrong Date: Fri, 27 Oct 2017 13:34:03 -0700 Subject: [PATCH] implement ergodox_left_leds_update in ergodox_ez Previously, this code was implemented in keymap.c, but I'm unaware of someone with a different implementation of this particular hack. [If someone has it, we can add another #ifdef in the future.] --- keyboards/ergodox_ez/ergodox_ez.c | 34 +++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) diff --git a/keyboards/ergodox_ez/ergodox_ez.c b/keyboards/ergodox_ez/ergodox_ez.c index 8337db666..8ada551ae 100644 --- a/keyboards/ergodox_ez/ergodox_ez.c +++ b/keyboards/ergodox_ez/ergodox_ez.c @@ -151,6 +151,40 @@ out: return mcp23018_status; } +#ifdef LEFT_LEDS +uint8_t ergodox_left_leds_update(void) { + if (mcp23018_status) { // if there was an error + return mcp23018_status; + } +#define LEFT_LED_1_SHIFT 7 // in MCP23018 port B +#define LEFT_LED_2_SHIFT 6 // in MCP23018 port B +#define LEFT_LED_3_SHIFT 7 // in MCP23018 port A + + // set logical value (doesn't matter on inputs) + // - unused : hi-Z : 1 + // - input : hi-Z : 1 + // - driving : hi-Z : 1 + mcp23018_status = i2c_start(I2C_ADDR_WRITE); + if (mcp23018_status) goto out; + mcp23018_status = i2c_write(OLATA); + if (mcp23018_status) goto out; + mcp23018_status = i2c_write(0b11111111 + & ~(ergodox_left_led_3<
