Greetings to all developers, I'm new to the world of stm32duino.
I need to send data with Usart, but I cannot use the Software Serial library with stm32f103.
Is there a similar library or what would you recommend me to do?
I am using stm32f103 I program with stlink.

Hi,
which core you used?
viewtopic.php?f=2&t=301
Why need specifically a software Serial? STM32 has several hardware Serial (Ex: STM32F103C8 has 3 USART)
The STM32 Core provides a SoftwareSerial library for compatibility but I do not advise to use it if you can use a hardware one.
For LibMaple core I don't know if it has a SoftwareSerial library.

i use stm32f102c8t6 with arduino ide.
i use Adafruit Ultimate GPS, LPS25HB pressure sensor and Xbee Pro S2C.
I need softwareserial library because i dont know how can i usart without this library.
maybe you can help me.

Many years ago, w/Roger's core when it had not diverged much from LeafLab's original work. It
may compile these days, but I hacked the Adafruit stuff at the time.

The libraries are in the zip download.
If using Linux, the #includes need to have the backslash '\' changed to slash '/' ... in fact, both Windozs and Linux respect the "slash" so no need to use the back-slash any more.
Code: Select all
