Nico Tonnhofer aeb98b557b STM32F411: cleanup code with using pinio.h macros. 2017-03-03 18:54:57 +01:00
Nico Tonnhofer 56c2238fef dda.c/dda_maths: add int_f_sqrt for controller with FPU 
very fast sqrt in hardware
also accurate dda->c for high steps/mm without overflowing
 2017-03-03 18:54:57 +01:00
Nico Tonnhofer 7fcb8fd20c pinio.h: rename _PULLUP_OFF also on STM32 to _PULL_OFF 
added also some information about possible modes
removed deprecated comment

Nico Tonnhofer 0cfc503c4a STM32F411: easy change system clocks 
- 96MHz
- 100MHz
- 108MHz

100MHz is standard now. 108MHz was possible on a first test, but is not recommended for real systems!

Nico Tonnhofer 7223c9dea8 ARM: split out spi-avr.c from spi.c 2017-03-03 18:54:57 +01:00
Nico Tonnhofer d9a350749d STM32F411: save cpu cycles are 160 
Also, first interrupt should not occur at 0.

Nico Tonnhofer 6f334be231 STM32F411: support inverted heater pin signals. 2017-03-03 18:54:57 +01:00
Nico Tonnhofer afc4c3e8e4 STM32F411: Allow non-PWM pins as heater output. 2017-03-03 18:54:57 +01:00
Nico Tonnhofer 423c5694d0 STM32F411: Respect configured PWM frequencies in heater-stm32.c 
Test: the PWM frequency on the scope should be similar to the
one configures in the board file with DEFINE_HEATER().
 2017-03-03 18:54:57 +01:00
Nico Tonnhofer 06c6aed23d STM32F411: Turn on only timers needed in heater-stm32.c 
Test: PWM pins work as before.

Nico Tonnhofer 12691b4488 STM32F411: Implement heater_set() in heater-stm32.c. 
Works very nicely from full off (M106 S0) to full on (M106 S255).

Test: M106 should work now as expected. M106 S0 should turn full
off, M106 S255 should turn full on, both without any spike on the
scope.

Nico Tonnhofer df78b8d826 STM32F411: implement heater-stm32.c partially. 
Like Traumflugs implementation at a fixed frequency of 1kHz and a fixed duty
cycle of 10%.

Nico Tonnhofer 75af589f43 STM32F411: comment out analog_mask and adc_channel for STM32 2017-03-03 18:54:57 +01:00
Nico Tonnhofer efd8279c1a STM32F411: implement DMA for ADC 
Eureka!!!
The STM32 has only one data register for all channels. So I want to use the ADC over DMA.
Issues are: It is not possible to stop the DMA or the ADC without uninit and init the hole parts.
We have more or less one option. Manually start the ADC.
So what we have now. We start the ADC after reading the values from DMA buffer. The ADC now make a conversion of all channels.
We can read also the values because it uses a double buffer mode. With that mode we can read the unused buffer.

Nico Tonnhofer 4cb6f85e3c STM32F411: implement analog-stm32.c 
It's not that easy like LPC. We need later an DMA to control all ADCs, because there is only one register to read the ADC.

Nico Tonnhofer c3a8b7fd06 ARM: rename analog-arm.c to add more ARMs 2017-03-03 18:54:57 +01:00

Nico Tonnhofer 42b26d9c20 STM32F411: get clock.c in. 
No code changes neccessary.

This code in ifclock(clock_flag_1s) in clock.c should give a nice,
accurate clock:

    static uint8_t minutes = 0, seconds = 0;

    seconds++;
    if ( ! (seconds % 60)) {
      seconds = 0;
      minutes++;
    }
    sersendf_P(PSTR("%su:"), minutes);
    if (seconds < 10)
      serial_writechar('0');
    sersendf_P(PSTR("%su\n"), seconds);

Current sizes are:

Nico Tonnhofer a798cfac34 STM32F411: get timer.c in, so far only with the system clock. 
This test code in SysTickHandler() should give you a rather
accurate clock with only a few seconds deviation per hour:

  #include "serial.h"
  #include "sersendf.h"
  void SysTick_Handler(void) {
    static uint32_t count = 0;
    static uint8_t minutes = 0, seconds = 0;

    count++;

    if ( ! (count % 500)) {   // A full second.
      seconds++;
      if ( ! (seconds % 60)) {
        seconds = 0;
        minutes++;
      }
      sersendf_P(PSTR("%su:"), minutes);
      if (seconds < 10)
        serial_writechar('0');
      sersendf_P(PSTR("%su\n"), seconds);
    }

Nico Tonnhofer 1954780892 STM32F411: rename arm-stm32f411xe.ld to cmsis-stm32f411xe.ld 
This is the start of renaming all CMSIS related files to
"cmsis-...".

Nico Tonnhofer b9107397b2 STM32F411: serial-stm32.c: allow sending arbitrarily long messages. 
On ARM we use only the 16 byte hardware buffer for sending and
receiving over the serial line, which is often too short for
debugging messages. This implementation works fine and still
neither blocks nor introduces delays for short messages.

Removed while-loop. Looks like we need some more us than the LPC?!? With +7us
we do not lose characters anymore.
