STLINK-V3SET teardown images 

Just received from mouser a brand new STLink V3.

Here cames a bit of teardown of it.

Powered by an STM32F723 BGA variant.

It has a pretty nice construction with insightful features (USB to CAN, I2C, SPI, JTAG, SVD, SWIM).

I would love to use this a general tool. (Patch AVRDude to flash AVRs with it, patch flashrom to flash random SPI flashes, etc.)

strreplace for EAGLE ULP 


string strreplace(string original, string toReplace, string replaceWith){
string ret = "";
string left = original;
while (strstr(left, toReplace) >= 0) {
ret += strsub(left, 0, strstr(left, toReplace));
ret += replaceWith;
left = strsub(left, strstr(left, toReplace) + strlen(toReplace));
}
ret += left;
return ret;
}

Custom Saleae Logic Analyzer plugin load fails on OSX with "Unable to 'dlopen' so/dylib " error 

One of our custom analyzer plugin started to fail to load after started using an std::set variable with the error above with the similar output from the Logic:

Solution:

Add -lc++ to the linker flags before the -lAnalyzer.

STM8 compiler comparison SDCC vs. Cosmic 

I have converted a project previously built with Cosmic to be compiled with SDCC.

The size results were really bad, the project cannot fit in the 8K memory of the STM8S003:

SDCC:

flash size: 6912 occupied: 8706 (125.95%) free: -1794 (-25.95%)

sensor size: 2092 (30.27%)
interrupt size: 1959 (28.34%)
signalprocessing size: 1577 (22.82%)
xlineslave size: 1309 (18.94%)
led size: 988 (14.29%)
init size: 253 (3.66%)
config size: 129 (1.87%)
delay size: 123 (1.78%)
seedbuffers size: 104 (1.50%)
main size: 86 (1.24%)
adc size: 86 (1.24%)


While Cosmic:

flash size: 6912 occupied: 6480 (93.75%) free: 432 (6.25%)

interrupt.o size: 1540 (22.28%)
sensor.o size: 1464 (21.18%)
xlineslave.o size: 802 (11.60%)
signalprocessing.o size: 688 (9.95%)
led.o size: 559 (8.09%)
ldiv.o size: 235 (3.40%)
init.o size: 222 (3.21%)
lmul.o size: 139 (2.01%)
config.o size: 131 (1.90%)
interrupt_vectors.o size: 128 (1.85%)
crtsi0.sm size: 80 (1.16%)
delay.o size: 73 (1.06%)
main.o size: 69 (1.00%)
adc.o size: 60 (0.87%)
seedbuffers.o size: 45 (0.65%)
imul.o size: 33 (0.48%)
lcmp.o size: 32 (0.46%)
lgadd.o size: 23 (0.33%)
lsbc.o size: 23 (0.33%)
lneg.o size: 21 (0.30%)
cmulx.o size: 20 (0.29%)
ludiv.o size: 20 (0.29%)
lgneg.o size: 19 (0.27%)
rtol.o size: 18 (0.26%)
lursh.o size: 15 (0.22%)
lgursh.o size: 14 (0.20%)
utolx.o size: 7 (0.10%)


The total flash size is just 6912 bytes because of the bootloader.
