From 99a3750a2cfd1da8cdd266ca9a0367f0c3a54092 Mon Sep 17 00:00:00 2001 From: Christian Walther Date: Sat, 24 Oct 2020 17:50:11 +0200 Subject: Fix lost board.SPI and board.I2C after explicitly deiniting them. After calling board.SPI().deinit(), calling board.SPI() again would return the unusable deinited object and there was no way of getting it back into an initialized state until the end of the session. --- shared-bindings/board/__init__.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'shared-bindings') diff --git a/shared-bindings/board/__init__.c b/shared-bindings/board/__init__.c index 6837fc41c..717698408 100644 --- a/shared-bindings/board/__init__.c +++ b/shared-bindings/board/__init__.c @@ -28,6 +28,12 @@ #include "py/runtime.h" #include "shared-bindings/board/__init__.h" +#if BOARD_I2C +#include "shared-bindings/busio/I2C.h" +#endif +#if BOARD_SPI +#include "shared-bindings/busio/SPI.h" +#endif //| """Board specific pin names //| @@ -45,7 +51,7 @@ #if BOARD_I2C mp_obj_t board_i2c(void) { mp_obj_t singleton = common_hal_board_get_i2c(); - if (singleton != NULL) { + if (singleton != NULL && !common_hal_busio_i2c_deinited(singleton)) { return singleton; } assert_pin_free(DEFAULT_I2C_BUS_SDA); @@ -69,7 +75,7 @@ MP_DEFINE_CONST_FUN_OBJ_0(board_i2c_obj, board_i2c); #if BOARD_SPI mp_obj_t board_spi(void) { mp_obj_t singleton = common_hal_board_get_spi(); - if (singleton != NULL) { + if (singleton != NULL && !common_hal_busio_spi_deinited(singleton)) { return singleton; } assert_pin_free(DEFAULT_SPI_BUS_SCK); -- cgit v1.2.3
