Re: user traps

ASSERT generates the ARM SVC instruction which is a software interrupt. The interrupt handler that is invoked is the one that is assigned to the address of the SVC interrupt handler (Traps.SVCVector). In a standard Astrobe installation the interrupt handler is the procedure Traps.SVCTrap. The assert...

Re: Delays

Unfortunately I have had no success with that - I'm probably just missing one of the many parameters that you need to take care of. Duh! I wasn't missing a parameter I just had Pin PC9 mode configured as Output Mode rather than an Alternate Function Mode. The MCO2 frequency on Pin PC9 measures as 4...

Re: Delays

(Sorry - I accidentally overwrote your previous reply) You can use the Crystal Freq (Hz) parameter if you want to target boards with different clock frequencies. You could then use the value to set all of the appropriate clock parameters in Main.mod. You would also need to put checks in your code to...

Re: Delays

The following code counts the number of 1000 uSec delays that occur during 1 second of time as recorded by the real-time clock. It returns exactly 1000: Clock.Init(); secs := 0; Clock.SetHMS(0, 0, 0); count := 0; REPEAT secs := Clock.Seconds() UNTIL secs = 1; WHILE secs # 2 DO Timers.Delay(usecTimer...

Re: GPIO and leaf procedures

By definition leaf procedures cannot call procedures. However, you can call SYSTEM.PUT directly if you want to perform GPIO operations in a leaf procedure. e.g. the Error procedure in the DramTest example lights the red LED before going into an infinite loop. PROCEDURE Error(); BEGIN GPIO.Put(LEDRe...

DRAM Tester

A 1983 Sage II 68000 computer I acquired last year was failing to boot with a RAM test error. Unfortunately the diagnostic only identified which of four 256K blocks was the first to fail. As there are 18 DRAM chips in each block it was not feasible to identify the bad chips(s) just by swapping them ...

Re: SPI and demo for a TFT Graphics Display

The Slide demo has been tested on both of the STM Cortex-M7 that we support: ⋅  STM Nucleo-144 F746ZG board ⋅  STM Nucleo-144 F767ZI board I used eight female-male jumper wires to connect the display to the board. The connections are listed in the comments in the source code file...

Re: macOS support

No. It would not be easier to support the Astrobe command line tools in a JVM environment.

Re: macOS support

If anybody who has the Professional Edition wanted to try the command-line compiler and linker on a macOS system they would need to install the necessary pre-requisites (i.e. the Microsoft .NET framework). I would be interested to hear of any problems and would try to help resolve them if I am able ...
