Test and example code suggestion.

Postby rew » Wed Jun 03, 2020 11:59 am

In most of the examples the start of the serial port looks like this:

Code: Select all

sdStart(&SD1, NULL);

sometimes the comment says that this will result in 38400-8-n-1 configuration (but most often not). That's all fine and dandy, but the code is also meant to be an example you can start from and start to modify.

Code: Select all

 * This is the configuration for the serial port. The current configuration here is also
 * the default, so instead of passing this structure passin "NULL" would also result in the same configuration.
static SerialConfig ser_cfg = {
sdStart(&SD1, &ser_cfg);

In the same vein I think there should be

Code: Select all

/* because we use the DISCOVERY board definition and that configures the default to be
 * correct in this case this is not necessary. But if you want to use it on a different UART/pin
 * this is how it is done.
palSetLinemode  (...., STM_ALTERNATE ());
